Family Ties and Corruption

Abstract We study the relation between conjugal family ties and
corruption. Our theoretical model shows that the population share
of people who have a desire to retain close ties with their
families (i.e., the extensive margin) has an ambiguous effect on
the level of corruption, due to the presence of conflicting
mechanisms. However, the strength of this desire among people who
want to retain close ties with their families (i.e., the intensive
margin) has an unambiguously negative effect on corruption. The
latter outcome finds support from our empirical analysis: Using
micro-level data, we show that, in contrast to conventional wisdom
and cross-country reflections, stronger family ties are negatively
correlated with a broad set of activities that measure
corruption.

1 Introduction Corruption is a phenomenon whose adverse social
and economic effects can be wide-
ranging (e.g., Mauro 1995; Tanzi and Davoodi 1998). For this
reason, the identification of
various factors that fuel corruption has held a prominent place
in the research agenda of
many fields, including economics. As a result, a large body of
work has pinpointed
several factors that are responsible for high levels of
corruption – factors that include
economic, administrative, historical, and cultural ones.1 Our
study contributes to a
further understanding of the cultural sources behind high
corruption, as it aims at
examining the role of family ties. Specifically, it focuses on
conjugal (or nuclear) family ties
– rather than extended kinship ties - and aims at investigating,
both theoretically and
empirically, their impact on people’s willingness to engage in
corrupt behaviour and,
therefore, the level of corruption.2
The results from existing empirical work on the link between
corruption and
family ties is rather mixed: While the study by Marè et al.
(2016) finds that family ties are
associated with higher levels of corruption, Ljunge (2015)
reports that family ties
promote civic virtues – among them, the disapproval of
corruption. In general, while the
link between family ties and corruption has already attracted
the interest of empirically-
oriented work, the existing literature lacks a systematic
theoretical study that identifies
possible mechanisms through which family ties affect people’s
attitudes towards
corruption. One of our study’s aims is to fill this gap in the
literature.
Given its focus on conjugal family ties, our theory borrows
elements from
Alesina et al. (2015) – the agents’ locational preference
contingent on their desire to retain
close ties with their families – and expands them by
incorporating public sector
employment, which gives the opportunity of illegal rent-seeking
through corruption.
From a certain perspective, our theoretical model delivers
mechanisms that explain why
1 This literature is very extensive and has traced several
factors, such as opportunities for rents and discretionary power
(Klitgaard 1988); regulation, taxation and below market-price
provision of goods (Tanzi 1988; De Soto 1989); and the level of
public sector wages (Haque and Sahay 1996) among others. Treisman
(2000) explores a series of determinants that are correlated with
corruption, such as legal origin and institutions, whereas Hauk and
Sáez-Martí (2002) and Barr and Serra (2010) emphasise the role of
culture and norms. 2 The difference between conjugal family and
extended kinship is that the former considers the nucleus of
parents and children whereas the latter considers an extended
network of relatives, clans etc. See Enke (2019) for a study that
investigates the economic implications of extended kinship
ties.

the effect of family ties on corruption can be ambiguous. On the
one hand, people’s
desire to retain strong family ties reduces the range of
high-productivity opportunities
to which they can be employed, due to their reluctance to reside
away from their
parents, hence tempting them to compensate for this shortfall
through the ill-gotten
gains of corrupt behaviour. On the other hand, however, the
utility cost that emanates
from the chastisement and the stigma attached to the revelation
of corrupt behaviour,
has a more pronounced effect on people who possess a sense of
strong family ties, thus
acting as a counter-incentive for them to seek illegal rents
through corruption. Overall,
when the measure of family ties is the population share of those
who abide by them,
family ties may be associated with either more or less
favourable attitudes towards
corrupt behaviour – and, therefore, with either higher or lower
incidence of corruption –
depending on which of the two opposing mechanisms prevails.
Our theory also offers another perspective that involves the
potential measure of
the strength of family ties. The argument is that, in addition
to the share of people who
have a desire to retain close ties with their conjugal families,
what is also important is
how strong this desire is. In other words, our point of view is
that both the extensive and
the intensive margins of family ties’ measurement merit
consideration. For that reason,
besides the prevalence of different family values among the
population, our model also
pinpoints another measure of family ties – i.e., the component
that quantifies the utility
accruing as a result of retaining close ties with one’s family.
Under this measure, the
relation between the strength of family ties and corruption is
unambiguously negative.
In other words, when the desire to retain close ties with the
family increases, the
incentive to be corrupt declines.
This latter mechanism is actually the focus of our empirically
strategy in
investigating the interplay between corruption and family ties.
We do not attempt to
establish causality, a task that is rather demanding with survey
data. Instead, we focus
primarily in highlighting the correlation between the two
variables, and in uncovering
the underlying mechanisms. Methodologically, we test our
reduced-form hypothesis
using micro-level data from the European Values Study (EVS) and
a variable developed
by Alesina and Giuliano (2010) as a means of measuring the
strength of family ties. Our
empirical results support the hypothesis that stronger family
ties are associated with
-

attitudes less favourable to corruption, thus they accord with
the empirical outcomes in
Ljunge (2015) and with broader arguments that stress the
importance of familial
experiences in determining civic values (e.g., Wilson 1993). Our
results are robust to
several different specifications, such as controlling for region
fixed effects that captures
even more unobservables, and to the use of different samples,
e.g., the World Value
Survey (WVS) instead of the EVS.
Despite the fact that there are reasonable arguments to support
an outcome
whereby family ties reduce the incidence of corruption, still
conventional wisdom and
casual observation may be at odds with this view. After all, a
simple observation of the
European continent, for example, can reveal that corruption is
more widespread among
countries in Southern Europe – in which strong family ties are
also more pervasive
among the population – compared to Northern European countries –
in which strong
family ties are not as pervasive. How can this observation
reconcile with our theoretical
and empirical results? To see this, recall that, in our
theoretical framework, it is possible
that while the share of agents with preferences for maintaining
close ties with their
conjugal families – a population measure – is positively related
to corruption, at the
same time the strength of the desire to maintain close family
ties is inversely related to
corruption. In this respect, our micro-level empirical approach
is primarily capturing
outcomes that are consistent with the latter mechanism, given
that our main source of
variation is across-individual variation, without being
necessarily at odds with cross-
country reflections on the issue. Indeed, we conduct an
individual-level analysis and our
results are derived after accounting for a wide range of
individual and country controls
such as country and year fixed effects, thus we obtain
within-country estimates. In other
words, we do not ignore other factors – on the contrary, they
are an important part of
the story and they are implicitly captured by the fixed effects.
Our approach, however, is
to highlight the micro-level factors. Therefore, our results
should be primarily
interpreted as suggesting that if two individuals live in the
same county and are thus
faced with the same institutional/historical/cultural background
of the country, then
those who have stronger desire for close family ties will be
less favourable towards
corruption.

Overall, our study contributes to two strands of the literature.
First, it contributes
to the literature that investigates the determinants of
corruption. As we stated earlier,
this literature is extensive and has identified several
economic, institutional, historical
and cultural factors (e.g., Klitgaard 1988; Tanzi 1988 De Soto
1989; Haque and Sahay
1996; Treisman 2000; Barr and Serra 2010). Second, it
contributes to the literature that
investigates the impact of family ties on various economic and
social outcomes.3 This
literature has identified the implications of strong family ties
for labour market
outcomes (Alesina and Giuliano 2010; Alesina et al. 2015),
geographical mobility
(Giuliano 2007; Alesina and Giuliano 2010), education (Duranton
et al. 2009), gender
roles (Alesina and Giuliano 2013), economic systems and reform
(Esping-Andersen 1999;
Brumm and Brumm 2017; Galasso and Profeta 2018), trust (Alesina
and Giuliano 2011),
as well as ideology and political participation (Todd 1983;
Alesina and Giuliano 2011).
At this point, it should be noted that there is also a
literature on the broader
measure of kinship, as described and studied in the seminal
paper of Enke (2019).
However, in his study he highlights the fact that “…Alesina and
Giuliano’s variable of
nuclear family ties is conceptually distinct from
anthropologists’ concept of extended kinship
ties…” (Enke 2019, p.974). Moreover, the kinship variable in
Enke (2019) comprises four
different elements, i.e., extended family, joint residence,
unilineal descent and clans – all
of which are applicable primarily to an ethnic group analysis,
hence they differ from the
type of family ties modelled and empirically tested in our
paper. We view the distinction
between the two types of family ties as instrumental since each
definition and approach
captures different aspects of the topic and thus different
mechanisms associated with it.
Our study is structured as follows: In Section 2 we develop a
theoretical model to
study the underlying mechanisms that link corruption with the
strength of family ties.
Section 3 presents our empirical analysis and findings, and
Section 4 concludes.
3 There is also a newly emerging literature on the long-run
determinants of family ties. For example, see Ang and Fredriksson
(2017).

2 Theory The model draws on Alesina et al. (2015) with regard to
its focus on conjugal family ties
(rather than extended kinship ties) and their aspect of
locational preference. We consider
an economy that is populated by a constant mass (normalised to
1) of couples who live
for three periods – childhood, youth and maturity. The
individuals who comprise a
couple are distinguished solely on the basis of occupational
characteristics, the details of
which will be discussed shortly. Nevertheless, each couple
shares the same personality
traits and preferences, and make all their decisions jointly.
The demographic structure is
simple, as each couple gives birth to a couple, and so on.
Henceforth, we shall be
referring to couples as ‘agents’.
Agents form their personality traits and adopt values and norms,
which will
ultimately determine their desire to maintain close ties with
their families, in their
childhood. In this study, we are not going to be explicit about
the process whereby
agents adopt these cultural traits. Instead, we shall assume
that a fixed fraction (0,1)f
of agents wish to retain strong family ties, whereas the
remaining fraction 1 f do not
have such a desire. This is a scenario where children simply
adopt their parents’ cultural
characteristics, hence allowing us to ignore any dynamics and to
consider a static
framework that focuses purely on the decisions made by agents
when they are young. In
what follows, agents are going to be distinguished by { , }j s w
where s stands for
agents who have a preference for strong family ties, while w
stands for agents whose
preference for family ties is rather weak (or even absent).
Young couples earn income, enjoy the consumption of (private and
public)
goods, and rear their children. There are two sources of income
for each couple because
the activity to which each individual will be engaged, with the
purpose of earning
income, differs. Particularly, one of them will operate as a
perfectly competitive supplier
of a privately-produced good; the other will be employed by the
public sector (e.g., as a
civil servant) contributing to the procurement of a
utility-enhancing public good.
-

Private Production
The producer of the private good will supply Y units of it,
meaning that this is also the
amount of income that accrues to agents as a result of private
production. We follow
Alesina et al. (2015) in assuming that the productivity of
private sector producers is a
function of the location in which agents decide to reside. If
agents are willing to move to
any location away from their parents’ place of residence,
private production will result
in (1 )hY ω y units of output with certainty, where , 0ω y . If,
however, agents restrict
themselves in residing to the location of their parents, private
production will result in
the same amount of output, i.e., (1 )hY ω y , only with
probability (0,1)π , whereas
with probability 1 π private production will generate lY y units
of output. One way
to justify this assumption is to think that people can have a
greater set of productive
opportunities, and a better match for their skills, if they are
more mobile in terms of
location.
Public Sector
The government distributes an amount of output to each civil
servant, with the
condition that these funds should be used as an input in the
operation of a project that
contributes to the procurement of a utility-enhancing public
good. In return, civil
servants receive a salary 0B for their services. Contrary to
private sector producers,
we assume that the productivity of individuals who work as civil
servants is not affected
by the location where agents reside. We will also assume that
the production of public
goods occurs prior to private production.4
The government also levies a (lump-sum) tax 0T from each agent,
and uses
the proceeds to finance its expenses for public sector salaries
and for the provision of
public goods. Using 0G to denote the amount devoted to public
goods’ provision,
and taking account the unit mass of agents, it follows that the
government’s budget is
given by T G B . We also assume that all items in the public
budget are tied to the
economy’s output by setting
B by , G gy , T τy , (1)
4 This assumption is innocuous for our results. See Footnote
9.

where , , (0,1)b g τ . Therefore,
τ g b . (2)
With the purpose of introducing the moral hazard problem that
will ultimately
generate the incidence of corruption, we follow Varvarigos and
Arsenis (2015) in
assuming that the delivery of public goods is possible through
two types of projects.
Type- H projects return either 0γ units of public goods with
probability (0,1)p or
(0, )β γ units of public goods with probability 1 p , for each
unit of output invested in
them. Note that the realisation of the state of nature is
independently distributed across
all Type- H projects. Type- L projects, on the other hand,
return ,δ β γ units of public
goods with certainty, for each unit of output invested in them.
As long as
(1 )pγ p β δ , a condition that is assumed to hold hereafter,
the expected return of
Type- H projects is strictly higher compared to the return of
Type- L projects. For this
reason, the government imposes a condition on the employment
contracts of civil
servants, obliging them to operate only Type- H projects.
Nevertheless, some civil
servants may have the incentive to invest only a fraction
(0,1)βδ of the funds allocated
to them in the operation of a Type- L project, resulting in an
overall return of βδ βδ
units of public goods per unit of funds allocated to the civil
servant. They do so while
making the false claim that all the funds available to them were
invested in the
operation of a Type- H project, which eventually had a bad
realisation of the state of
nature. Doing so allows them to gain private rents, amounting to
a fraction 1 βδ
of the
funds that they should have invested in the first place.
Nevertheless, the authorities may detect their malfeasance. In
the event that the
authorities detect and prosecute a case of corruption, the civil
servant’s penalties involve
the loss of his salary, in addition to the loss of his
ill-gotten gains. Furthermore, the
punishment, stigma and shame associated with the revelation of a
civil servant’s
misconduct is an impediment to the couple’s prospects of
enjoying activities such as
consumption and – for those with preferences for strong family
ties – being close to their
parents. For example, legal proceedings, the stigma of being a
convicted fraudster and
-
9
the possible imprisonment can impinge on the number and the
quality of interactions
with the nuclear family. As we shall see shortly, these
emotional costs entail a
proportional loss in utility.
A counter-argument could be that interactions with the close
family may be less
affected by issues such as legal proceedings, imprisonment,
reputational damage etc.,
than interactions with acquaintances and friends, hence living
near parents may be an
attenuating factor to these costs. Our focus, however, is on
people who have an
increased desire to be close to – and to interact with – their
parents. As long as the
number of such interactions and the circumstances/environment
under which these
occur are affected by these issues, then they will surely
impinge on the utility increment
that people with strong family ties enjoy from being close to
their parents.
Let us assume that the probability of a Type- j civil servant
being apprehended
and punished for his transgression, denoted Μ j , is uniformly
distributed on [0,1]
across all civil servants of the same type (i.e., { , }j s w ).
Similarly to Varvarigos (2017),
this form of heterogeneity captures the varying abilities of
corrupt civil servants in
avoiding the revelation of their misdemeanour. For example, it
may capture varying
degrees of vigilance and care in avoiding lifestyle choices and
behaviour that could
signal their excessive income. It may also capture varying
degrees of networking with
people who can assist them in eluding detection and punishment.5
With the purpose of
simplifying the analysis, we shall employ the following
functional form for the
probability that a Type- j civil servant’s nefarious activities
will be eventually revealed:

If we denote the number of civil servants who will decide to be
corrupt by Θ , it
follows that the amount of public goods offered by the public
sector, denoted a , can be 5 Another underlying assumption here is
that the probability of detection is independent of the civil
servant’s type (i.e., j s or j w ). This is done purely as a means
of analytical simplicity, with minimal cost to generality (if
any).

(1), this expression can
be rewritten as
[(1 Θ) ( ) ]a gy p γ β β . (5)
Preferences
As we indicated previously, the decision to reside in the close
vicinity of the agents’
parents will entail a productivity cost, manifested in the
potential loss of income from
private production. The reason why agents may still decide to do
so however, relates to
their preferences on the issue of family ties. Particularly,
agents who have a desire for
maintaining close family ties will either enjoy a utility gain
if they reside in their parents’
location, or incur a utility cost if they move away from it. On
the contrary, agents who
have not adopted values that are supportive to family ties, do
not gain nor lose any
utility as a result of their choice of residence when they
become adults. Formally, the
Type- j agents’ utility is given by
( Φ )(1 )j j jU c S a , (6)

Note that the specification in (6) assumes that the deleterious

of view, this assumption eliminates strategic considerations on

consider an extension where agents who uphold strong family ties
make income transfers to their parents. The main results remain
qualitatively identical, meaning that the absence of transfers from
the main framework is not such a critical factor for the model’s
results and implications.

corrupt among Type- w and Type- s civil servants.7 Such
strategic effects would impose
significant mathematical complication, thus obscuring the
clarity of our analysis without
adding anything to its main implications.
2.1 The Decisions of Type-w Agents
Let us consider agents who do not have a desire to retain close
ties with their families
(i.e., j w ). Taking account of (6)-(8), it follows that they
will choose to move away from
their parents’ location, thus earning (1 )hY ω y units of income
from private
production. As a result, if the civil servant is honest in his
involvement with public
goods delivery, the agents’ utility will be
honest honestw wU c a , (9)
where
(1 )honestw hc Y B T ω g y , (10)
is the agents’ budget constraint. If the civil servant is
corrupt, the agents’ income will be
augmented by the amount of ill-gotten gains that emanate from
his rent-seeking. In the
event that he is detected, however, he will lose all the gains
from his employment in the
public sector – the salary and the proceeds from illegal
rent-seeking – while he and his
partner will face the utility-reducing consequences of the
revelation of his fraudulent
behaviour. Under such circumstances, the Type- w agents’
(expected) utility is:
, ,(1 Μ ) Μ (1 )corrupt corrupt not detected corrupt detectedw w
w w wU c c σ a . (11)
Defining the composite term (0,1)βzδ
, we can substitute (1) and (2) to express the
budget constraints as follows:
1corrupt ,not detectedw hc Y B z G T (1 )ω gz y , (12)
corrupt ,detectedw hc Y T (1 )ω g b y . (13)
Next, we can combine (3), (4), (10), (12) and (13) to rewrite
the utility functions in (9) and
(11) as
7 Specifically, strategic considerations would emerge because
each person’s incentive to be corrupt would depend on the provision
of public goods, thus on the actions of all other agents who decide
whether to be corrupt or not.

respectively.
The Type- w civil servant will be corrupt and engage in illegal
rent-seeking as
long as the agents’ (expected) utility from doing so is at least
equal to the utility that
applies if he decides to abscond from any wrongdoing, i.e., if
corrupt honestw wU U . Therefore,
equating (14) and (15) defines a critical value

such that civil servants for whom w wμ μ will be corrupt,
whereas those for whom
w wμ μ will decide to remain honest. In other words, wμ is also
the number of
corrupted Type- w civil servants.
2.2 The Decisions of Type-s Agents
Now, let us consider agents who have a preference for retaining
close ties with their
family (i.e., j s ). Given the characteristics of the model,
these agents may actually have
the incentive to stay in the location of their parents, despite
the potential loss of income
from such a decision. If they do so, the agents’ budget
constraint, following the
substitution of Eq. (1) and (2), will be given by

locations, their budget
constraints will be identical to those of Type- w ones, i.e., (1

, (1 )corrupt not detectedsc ω gz y and corrupt ,detectedsc (1
)ω g b y . Together with (3), (4), (6)-(8)
and (17)-(19), it follows that the agents’ (expected) utility
from consumption, depending
on whether the civil servant is honest or corrupt, can be
written as

, (23)
if they move away from it.
With the purpose of improving the focus of our analysis,
henceforth we shall
adopt the approach of Alesina et al. (2015) by imposing a
condition which guarantees
that the agents who have preferences for maintaning family ties
will find optimal to
reside close to their parents. It should be noted that this
assumption accords with
evidence showing that strong family ties reduce geographical
mobility (Giuliano 2007;
Alesina and Giuliano 2010). Formally, a sufficient condition
is
[ (1 ) (1 ) (1 ) ] ˆ2
g z π ω σ πω g b b yφ φσ
. (24)
Given the condition in (24), agents with a desire for strong
family ties will always choose
to remain in their parents’ location, meaning that their utility
will be given by either (20)
or (21).8 As a result, we can use these expressions to examine
the civil servant’s conduct
while in public office. In other words, the critical value sμ
for which corrupt honests sU U can
be obtained as follows:
8 The condition in (24) guarantees that the lowest level of
utility associated with staying in the parents’ location (i.e.,
when a civil servant is corrupt but apprehended with certainty)
exceeds the highest level of utility associated with residing to a
different location (i.e., when a civil servant is corrupt and
evades detection with certainty).

According to (25), civil servants for whom s sμ μ will engage in

is also the number of

2.3 The Impact of Family Ties on the Level of Corruption
We can combine (16) and (25) to express the total number of
corrupt civil servants as

(28)
Next, we define the composite term
(1 )φ π ωy , (29)
which allows us to get the following results:

We can formalise the implications on the impact of preferences
for strong family
ties among the population on corruption through
Proposition 1. The impact of an increase in the population share
of people with a desire to retain
close family ties has an ambiguous (i.e., either negative or
positive) effect on the incidence of
corruption.
Proof. It follows from Lemma 2. ■
The ambiguity emanates from the fact that, for agents whose
values are
conducive to strong family ties, the utility costs associated
with a civil servant’s
misconduct generate two conflicting effects on the incentive to
be corrupt. On the one
hand, the possible income loss incurred because of their desire
to reside close to their
parents, while relinquishing more productive opportunities
elsewhere, mitigates the loss
in the marginal utility of consumption induced by chastisement
and stigma. This is a
mechanism through which strong family ties cause a higher
incidence of corruption.9 An
alternative interpretation is that, for agents who abide by
strong family ties, the ill-
gotten gains of corruption are also viewed as the means of
covering the shortfall in
9 Qualitatively, our results would be similar in a scenario
where the civil servants’ decisions and the delivery of public
goods materialise after the production of private goods. This is
because, with a fraction 1 π of Type- s agents earning y from
private production, instead of (1 )ω y , the average (private)
income of this group would still lack behind the average (private)
income among Type- w agents.

productivity and income. On the other hand, however, the utility
costs that stem from
the revelation of a civil servant’s wrongdoing, also mitigate
the agents’ enjoyment from
residing close to their parents. This expected loss in utility
acts as a disincentive to
engage in nefarious activities while in public office, hence
generating a mechanism
through which family ties cause a lower incidence of
corruption.
Note, however, that in addition to distribution of different
types of family values
among the population, our model includes an additional measure
of the strength of
family ties. This is captured by the parameter φ , i.e., the
utility value for agents who
enjoy retaining close ties with their families. In other words,
this is a measure of how
strong is the feeling of family boding among the people who
possess preferences for
retaining ties with their conjugal family. In order to
investigate its implications on the
model’s main outcomes, consider the result in
Lemma 3. It is Θ( , ) 0f φφ
.
Proof. Given (27), we have ( ) 0sθ φφ
. Therefore, from (26) it is straightforward to
establish that Θ( , ) ( ) 0sf φ θ φ fφ φ

Now, we can establish the impact of this measure of family ties
on corruption by
means of 10
10 On a side-note, it should be clear that the impact of family
ties on corruption also dictates the impact on the economy and
welfare through the effect on the provision of public goods a .
After all, corruption is manifested through the deliberate choice
of less productive projects for the procurement of
utility-enhancing public goods. Consequently, any factor that fuels
corruption is bound to reduce the effectiveness of the public
sector’s production activities, by limiting the amount of goods
delivered per unit of public investment. To see this, use Eq. (28)

Proposition 2. The impact of a stronger desire for family ties,
among those with preferences for
retaining close ties with their families (i.e., a higher φ ), on
corruption is unambiguously
negative.
Proof. It follows from Lemma 3. ■
In terms of intuition, the higher is φ , the stronger is the
expected utility loss for
agents who contemplate the ill-gotten gains of corruption, but
who also consider the
possible repercussions, including the non-pecuniary ones (e.g.,
imprisonment, shame
etc.), from the revelation of this wrongdoing. For this reason,
the strength of the desire to
maintain close ties with the conjugal family alleviates the
incentive to engage in corrupt
behaviour.
A counter-argument to the negative effect of strong family ties
on the incentive to
be corrupt has to do with the redirection of economic resources
(including the ‘spoils’ of
illegal rent-seeking) towards the immediate family. In the
context of our model, consider
agents who care for their parents through the provision of
financial resources, as long as
they abide by strong family values. The argument is that, in
this case, family ties may
increase the incentive to be corrupt because this will increase
their ability to provide for
their families. Although this could be a valid mechanism, the
extent to which it can
completely revert our existing results is questionable. For
example, consider a
modification where the agents’ utility component 1 ( ) ( )κ φ κ
φs sc c t ( ( ) [0,1)κ φ , (0) 0κ ,
( ) 0κ φ ) includes own consumption ( sc ) and a financial
transfer to their old parents ( t )
– with corresponding modification to the budget constraint(s).
If I denotes the agents’
total resources (income from employment plus ill-gotten gains –
if any) then
(1 ( ))sc κ φ I , ( )t κ φ I and sc ςI (( ) 1 ( )( ) (1 ( ))κ φ
κ φς κ φ κ φ ) in equilibrium. In other
words, agents optimally give a fraction ( ) [0,1)κ φ of their
total economic resources to
their parents – a fraction that is increasing in the strength of
family ties – and keep the
remaining fraction 1 ( )κ φ for their own consumption. In
comparison to the model
presented in this study, the utility term sc is sc ςI instead of
sc I , thus the
mechanisms and results will survive with little change to the
model’s implications.

18
There are some important implications from the preceding
analysis. Firstly, our
model provided a theoretical foundation for circumstances when –
contrary to the
conventional wisdom that would view strong family ties as a
fillip for corruption -
factors that are relevant to strong family ties reduce the
incidence of corruption. The
second, and equally important in our opinion, can be clarified
through
Proposition 3. The measure of family ties can be crucial in
determining its impact on
corruption. It is possible that a higher population share of
people with preferences for retaining
family ties increases the willingness to be corrupt, whereas, at
the same time, a stronger desire for
family ties, among those with preferences for retaining such
ties with their families, reduces the
willingness to be corrupt.
Proof. It follows from the implications of Proposition 1,
Proposition 2, and Lemma 2 for
ˆ( , )φ φ φ . ■
In other words, the ambiguity with respect to the impact of
family ties on
corruption is not only related to the conflicting underlying
mechanisms, but it may
extend to the measure of family ties as well. This is because
what matters is not only
whether people have a desire to retain close ties with their
families, but also how strong
this desire is. The next section presents an empirical analysis
that uses micro-level data
to test the reduced-form hypothesis of a relation between the
strength of family ties and
the approval of corrupt behaviour.
3 Empirical Analysis Our empirical analysis focuses on testing
outcomes that are more closely related to the
underlying message of Proposition 2. Furthermore, the
micro-level of our analysis
allows us to discuss several other elements of the model as
well.

19
3.1 Individual-Level Data and Empirical Strategy
In this section, we estimate the impact of family ties on
corruption-related attitudes at
the individual level. We employ the measure employed in Alesina
and Giuliano (2010)
that captures the strength of conjugal family ties. As already
highlighted above, we
totally abstract from kinship and in-group interaction
considerations. Our measure is
actually capturing the degree of love, affection and respect as
shaped within families.
We thus use data from the European Values Study (EVS). The EVS
is a large-scale cross-
national survey with four waves covering the 1981-2008 period.
In our study we use
data from all four waves wherever available. Overall, a total of
48 countries are included
in the cumulative dataset based on the four EVS waves.
Family Ties
In line with the benchmark studies that study the role of family
ties (e.g., Alesina and
Giuliano 2010) we use three questions to construct the family
ties index. The first
question asks how important family is for the respondent’s life.
Answers vary from 1-4
with “1” indicating that it is not important at all and “4”
indicating that family is very
important. The second question asks whether love and respect to
parent is taken as
given or whether it should be earned: The value of “1” indicates
that it should be earned
while the value of “2” indicates that it should always be taken
for granted. The third
question asks whether parents should fulfil their
responsibilities towards their children
at the expense of their own well-being: The value of “1”
indicates that they should not
sacrifice their own well-being whereas “2” indicates that they
should do the utmost best
for their children.
It should be noted that, in the original data from the EVS,
answers with higher
scores indicate a lower strength of family ties. To avoid
confusion and
misunderstanding, we have transformed the variables in the
manner described
previously. Hence, in all three questions, higher values
correspond to stronger family
ties. Furthermore, note that, in order to reduce the number of
variables and to combine
the three components to a single variable, our approach is to
conduct a principal
component analysis and to employ the first component as the
explanatory variable.
-
20
Corruption-Related Attitudes
In order to measure corruption-related attitudes at the
individual level, we use four
different questions whereby respondents are asked whether they
justify the following
acts: cheating on taxes; claiming state benefits (without being
entitled to); accepting a
bribe; and avoiding paying fare on public transport. Each
variable takes values from 1 to
10 with 1 corresponding to “never” and 10 corresponding to
“always”. Thus higher
values of these variables are associated with more favourable
views – and, therefore, a
greater inclination – towards corruption.11
A crucial point concerns the use of these measures as proxies
for corruption. We
justify this approach on the basis of the existing literature
and our own correlations. As
far as the existing literature is concerned, there are a number
of studies that have also
employed similar measures, extracted from the EVS and the WVS,
as proxies for
corruption. For example, Torgler and Valev (2010) and Litina and
Palivos (2016)
associate corruption with measures of bribe acceptance and tax
cheating, while
Azariadis and Ioannides (2015) do the same with unentitled
benefits claims. With regard
to our own correlations, we have found that, in most cases,
these measures (when
aggregated at the country level) have a positive correlation
with cross-country measures
of corruption, such as the Corruption Perceptions Index or the
ICRG Corruption
Index.12,13 There are a few comments worth making here. Although
the avoidance of
paying for public transport is not an obvious signal of
corruption, it still seems to
11 It is important to note that our results are the same if we
use any other question related to cheating or corruption, e.g., how
justifiable it is to buy stolen goods, and how justifiable it is
for people to keep money they found. However, we view these
questions as less relevant to our study and we thus do not
incorporate them in our analysis. 12 The following table reports
correlation coefficients between each measure of attitudes and two
widely known measures of corruption, i.e., the ICRG index and the
CPI index, averaged over the period we examine. Note that the ICRG
and CPI indices are inverse ones, i.e., lower values indicate more
corruption.

13 These proxies for corruption are also based on corruption
perceptions. However they are aggregated at the country level and
they combine information from several different sources. As such
they are generally perceived as country-wide measures that proxy
corruption as closely as possible.

correlate positively with actual measures of corruption.
Perhaps, it reflects a general
mindset whereby it is acceptable to promote private gains at the
expense of the ‘public’
good. It is exactly for this reason that we also find the lack
of a significant correlation
between the attitudes towards tax cheating and the corruption
indices (despite the
correlation coefficient having the correct sign). This may
reflect the fact that, when
considering tax morale, corruption is only one of its many
facets that include personal
views on the fairness of the tax system, the need for
redistribution etc. Nevertheless, we
still retain this measure in our analysis, since the link
between tax morale and corruption
is widely documented and accepted in the literature (e.g.,
Togler 2014).14
Reduced-Form Specification
Our main empirical analysis focuses on testing a hypothesis that
is conceptually closer to
the underlying message of Proposition 2, as it considers the
impact of the intensive
margin of family ties. We estimate the reduced-form
specification term
0 1 2ict ict ict c t ictCA a a FT a Controls I R ε . (30)
where ictCA denotes the attitudes towards corruption of an
individual i who lives in
country c and participates in round t , and ictFT is the measure
of family ties, i.e, the
principal component of the previously mentioned variables. The
variable ictControls is a
vector of individual-level controls including age, age squared,
gender, education,
religion and employment status. The term cI denotes country
fixed effects and aims to
capture unobservables associated with the country in which
individuals reside, and tR
denotes EVS round fixed effects, thus capturing unobservables
related to the timing of
the interview that are common across countries. Finally, ictε is
the error term.
Naturally, our coefficient of interest in Eq. (30) is 1a . This
will identify the impact
of family ties on the proxies of corruption-related attitudes,
accounting for other
individual characteristics as well as country and year effects.
A point worth mentioning
is that the country fixed effects absorb elements that are
explicitly mentioned in the
model, such as the role of government and the level of public
goods. This does not imply
14 In the same line of reasoning, we also confirmed our results
using other measures of misbehaviour (related to stolen goods or
lost money). As mentioned previously, these are not reported here
as they are not particularly relevant to our study.
-
22
that these factors do not play a role in our empirical analysis.
On the contrary country
fixed effects are crucial in terms of identification, precisely
because they capture the
important role played by differences across countries in all
these respects. We just net
out these effects via the use of fixed effects so as to uncover
the role played by family ties
on corruption, conditional on all these controls.
“Should I Stay or Should I Go?”
Once we obtain the reduced form results, we make a further
attempt to nail down one of
the important characteristics of our theoretical model, i.e.,
the proximity to the family in
terms of location. We argue in the model that people who have
stronger ties with their
family may choose to stay close to them at the expense of their
productivity, while those
with looser family ties are more likely to change location –
which ultimately results in
higher productivity as already argued in Alesina and Giuliano
(2010).15
According to Proposition 2, the impact of the strength of family
ties on
corruption is unambiguously negative. Based on this prediction,
we expect that if we
split the sample into those who stay vs those who leave their
parents’ location, the
former will be the ones who are primarily driving the result of
the decline in corruption.
The EVS allows us to identify people who move across NUTS
regions. There is one
question asking them in which NUTS region they lived when they
were aged 14 and in
which NUTS region they currently live. We thus assume that the
NUTS region at age 14
is the region in which they lived with their parents and the
current one is the new
residency most likely chosen for occupational reasons. Of
course, we cannot preclude
the family moving along with the respondent. Nevertheless, we
treat these deviations as
non-systematic as we do not see any plausible arguments to
suggest anything systematic
in such cases. Furthermore, we restrict our sample of movers and
stayers to working age
population aged 18-65.16
15 As mentioned previously, the adoption of this characteristic
in our theoretical framework follows Alesina et al. (2015). 16
Below we present the table of the summary statistics for stayers vs
leavers for the family ties variable and for the strength of family
ties variable. We observe than, in line with our model assumptions,
stayers manifest both stronger family ties and have lower income as
compared to leavers.
-
23
Given the above, we estimate the following equation:
0 1 1 2ict ict stayers ict leavers ict c t ictCA a a FT I a FT I
a Controls I R ε . (31)
The notation is exactly as in Eq. (30). The only difference lies
in the terms 1 ict stayersa FT I
and 1 ict leaversa FT I which are the interaction terms obtained
for the measure of family ties
in each regime, i.e., staying in the same NUTS or moving to a
different NUTS. In line
with our theory, we expect to obtain a different coefficient for
each group. Moreover, we
expect these differences to appear in the magnitude of these
coefficients – not in their
sign.
3.2 Empirical Results
Benchmark Specification
Table 1 reports estimates on the impact of the measure of family
ties on attitudes
towards corruption. The dependent variable in Column (1) is
“Justifiable: Cheating on
taxes”; in Column (2) is “Justifiable: To claim state benefits
(without being entitled to them)”;
in Column (3) is “Justifiable: Accepting a bribe”; and in Column
(4) is “Justifiable: Avoiding
fare on public transport”. The analysis controls for the full
set of relevant demographic,
socio-economic and household characteristics (i.e., age, age
squared, gender, education,
religion and employment status), as well as the EVS round and
country fixed effects. In
all four columns we find that stronger family ties are
associated with less favourable
attitudes towards corruption. In Table 1 Line II reports the
logit model coefficient
whereas, in terms of magnitude, the coefficients reported in
Line I are standardised beta
coefficients. Their range of values lies mostly around -0.1
suggesting that a unitary
change in the standard deviation of the family ties measure is
associated with a standard
deviation change of around -0.1 in most of the measures of
corruption. Overall, these are

not very strong effects, at least not for the full sample (as we
shall see shortly, they will
become stronger once we distinguish between people who leave
their parents’ location
and people who stay in it). Nevertheless, they are systematic
and emerge in all different
specifications, even after having controlled for several
demographic, country and time-
invariant characteristics.

Summary: This table establishes that stronger family ties are
associated with less favourable attitudes towards corruption. The
analysis controls for individual characteristics such as age, age
squared, gender, educational level, employment status, religious
denomination as well as for EVS round and country fixed effects.
Notes: (i) the attitudes-related variables (“justifiable to: cheat
on tax; claim state benefits; accept a bribe; avoid transport
fare”) take values from 1-10 with 10 indicating “always
justifiable”; (ii) the “family ties” variable is the principal
component of three variables, “how important in family in your
life”, “love and respect parents: always/earned”, “parents’
responsibilities to their children: at expense of/not sacrifice own
well-being”. Higher values of the variable indicate stronger family
ties; (iii) Robust standard error estimates, clustered at the
dimension of the country of origin, are reported in parentheses;
(iv) *** denotes statistical significance at the 1% level, ** at
the 5% level, and * at the 10% level, all for two-sided hypothesis
tests.
Table 1A reports the coefficients when we distinguish between
each group
explicitly. We observe that in all four columns the coefficient
is negative for both groups.
Moreover, with the exception of Column (2), where we have the
measure for claiming
state benefits, in all other cases it is the group of people who
never moved away from
-
25
their family’s location that has a stronger effect on
corruption. The coefficients are
expressed in standardized beta units and are around the value
-0.20 for those who stay
and -0.12 for those who leave (always with the exception of the
measure of state
benefits). In other words, a unitary standard deviation increase
in the principal
component of family ties is associated with up to a 0.20
standard deviation reduction in
our measure of corruption. This is a rather non-trivial effect.
To make it more
comprehensible, think that a unit change in the measure of
family ties, which ranges
between -5 and 0.8 (negative values appear due to the use of
principal component
analysis), is associated with a 0.9 change in the measure of
corruption, which ranges
between 1 and 10.

Summary: This table distinguishes the effect of family ties on
corruption based on the status of individuals, i.e., it separates
leavers from stayers. The analysis shows that the effect of stayers
is stronger than that of leavers. The analysis controls for
individual characteristics such as age, age squared, gender,
educational level, employment status, religious denomination as
well as for EVS round and country fixed effects. Notes: (i) the
attitudes-related variables (“justifiable to: cheat on tax; claim

from 1-10 with 10 indicating “always justifiable”; (ii) the “family

Robustness
Table 2 replicates the analysis in Table 1 by adopting a more
stringent specification.
Specifically, we employ a full set of regional fixed effects at
the NUTS 2 level. The reason
-
26
why we do not adopt this specification from the outset is
because we have significantly
fewer observations. Importantly though, the results remain
highly significant and
similar to the benchmark specification.
Table 3 tests the robustness of the explanatory variable by
employing another
measure that is widely used in this literature. This is the sum
of the three variables that
are used as measures of the strength of family ties, as opposed
to their principal
component. To do this, we first make the three variables similar
in terms of scale – in
this case, we bring them to a scale from 1 to 2 – with higher
values still indicating
stronger family ties. Subsequently, we use their sum instead of
the first component.
Columns (1) to (4) refer to the same dependent variables as in
Table 1 and they use the
same full set of controls. The results are – qualitatively and
quantitatively – very similar.
It should be noted that, although not reported here, similar
results are also obtained if,
instead of their sum, we use each of the three measures that are
incorporated in the
family ties index separately.
Table 4 tests the robustness of the benchmark analysis, using
the sample from the WVS
instead. All the variables and the controls are defined in the
same exact way, given that
the two surveys (EVS and WVS) are standardised in terms of
questions. The results are
strikingly similar both qualitatively and quantitatively.

4 Conclusions This purpose of this paper was to contribute to a
further understanding of issues
surrounding the relation between family ties and corruption. Our
theoretical model
showed that the overall effect of family ties on the incentive
to be corrupt – and,
therefore, on the incidence of corruption – can be ambiguous due
to the presence of
conflicting mechanisms. Our theory also pinpointed the
possibility that the impact on
corruption may be quite different, depending on the what
measures family ties – either
the population measure of the share of agents who abide by a
desire for maintaining
close family ties, or the micro-level measure of how strong the
desire for close family ties
actually is. This is a point with major implications, as it
offers a theoretical foundation on
why the conventional wisdom entailing cross-country reflections
may be at odds with
the outcomes of micro-level empirical investigations.
The empirical approach we adopted belongs to the latter
category, as it used
micro-level data to examine the effect of family ties on the
approval of activities that
proxy for corruption – activities such as bribery, tax evasion
etc. Our empirical results
verified that, at the individual level, stronger family ties are
associated with reduced
corruption, thus offering credence to the relevant result from
our theory.
Naturally, our theoretical model is stylised in many respects,
in order to ensure
its analytical tractability and the clarity of the intuition. As
a result, while it directs
attention to some intuitive mechanisms, unavoidably it does not
incorporate other
examples that can identify additional links on the relation
between family ties and
corruption. One such example is nepotism. It should be noted,
however, that this is not a
major shortcoming since our focus is on the strength of conjugal
family ties. Issues
pertaining to nepotism would be more relevant to an
investigation of extended kinship
ties and their relation to corruption. Another issue on which
our theory is not explicit is
the cultural transmission process for characteristics such as
the preferences for retaining
strong family ties or the attitudes towards corruption. Given
the underlying empirical
motivation, we opted for a simple static model that focuses on
the relation between the
two variables of interest (family ties and corruption) without
undermining the clarity of
the mechanisms through the addition of cultural transmission
dynamics. This by no
-

means imply that the issue of cultural transmission is less
important. On the contrary, it
certainly represents a worth-pursuing avenue for future
research.

Appendix A: Variable Definitions and Sources
A.1 EVS and WVS Variables
Family Ties
Family Ties (Principal Component): We use three questions to
construct the family ties
index. The first question is “How important is family in your
life?”. Answers vary from 1-4
with 1 indicating “not at all important” and 4 indicating “very
important”. The second
question asks whether love and respect to parent is taken as
given or whether it should
be earned. 1 indicates that it should be earned and 2 that it
should always be taken for
granted. The third question asks whether parents should fulfil
their responsibilities
towards their children at the expense of their own well-being. 1
indicates that they
should not sacrifice their own well-being and 2 that they should
do the utmost best for
their children.
Overall, in all three questions higher values indicate stronger
family times. In
order to reduce the number of variables and to combine the three
components to a single
variable we conduct a Principal Component Analysis.
Family Ties (Sum): This alternative measure of family ties is
the sum of the same three
questions. To take the sum we give the same scale to all the
variable, i.e., from 1 to 2,
with higher values indicating stronger family ties.
Attitudes Related to Corruption
Justifiable: To Cheat on Taxes: This variable answers to the
question “To what extend do
you find it justifiable to cheat on taxes?” The variable takes
values from 1 to 10 with 1
denoting “never” and 10 denoting “always”.
Justifiable: To Claim Benefits: This variable answers to the
question “To what extend do
you find it justifiable to claim benefits one is not entitled
to?”. The variable takes values from
1 to 10 with 1 denoting “never” and 10 denoting “always”.
-
33
Justifiable: To Take Bribes: This variable answers to the
question “To what extend do you
find it justifiable to take bribes?” The variable takes values
from 1 to 10 with 1 denoting
“never” and 10 denoting “always”.
Justifiable: To Avoid Fare on Public Transport: This variable
answers to the question
“To what extend do you find it justifiable to avoid fare on
public transport?” The variable takes
values from 1 to 10 with 1 denoting “never” and 10 denoting
“always”.
Individual Controls
Age: The age of the respondent.
Female: A binary variable taking the value of 1 if the
individual is female and 0 if the
individual is male.
Education: Education is an ordered variable taking values from
1-3 with 1 denoting
“tertiary completed”, 2 denoting “secondary completed” and 3
denoting “primary completed”.
The same classification is used for the controls of paternal,
maternal and spouse
education.
Religion: Religion takes nine different values each associated
with a different religious
denomination.
Employment Status: The employment status of the respondent is a
categorical variable
taking values from 1-4 as follows: 1 is “full-time”, 2 is
“part-time or self-employed”, 3 is “not
participant (student, retired, other)” and 4 is
“unemployed”.
Stayers vs Leavers: The EVS allows us to identify people who
move across NUTS
regions. There is one question asking them in which NUTS region
they lived when they
were aged 14 and in which NUTS region they currently live. Based
on this variable we
construct an index that takes the value 0 if the individual
lives in the same NUTS as the
one he lived when they were 14 years old and the value 1
otherwise.

A.3 Country-level Variables
Corruption
CPI: We use the Corruption Perception Index (CPI) as a proxy for
corruption at the
country level. The variable takes values from 1 (least corrupt)
to 10 (most corrupt). We
have rescaled the original index for consistency with the
individual measures of
corruption.
ICRG. We use the ICRG measure of corruption as a proxy for
corruption at the country
level. The variable takes values from 1 (least corrupt) to 6
(most corrupt). We have
rescaled the original index for consistency with the individual
measures of corruption.
